Let's do a little comparison: two motorcycle martial artists and two trophy-collecting rogue mercenaries. Lockdown kills Prowl's sensei and Airachnid kills Arcee's first partner. Prowl and Arcee both have personal beefs with their arch-nemeses as a result. Arcee and Airachnid's rivalry echoes that of their Animated counterparts Prowl and Lockdown, but do we prefer the fembots or the cyber-ninjas? I wouldn't be surprised if Arcee and Airachnid's rivalry were to operate in a reverse of Prowl and Lockdown's. Where Prowl and Lockdown worked together (in "A Fistful of Energon") before becoming arch-enemies (in "Five Servos of Doom"), I could see Arcee and Airachnid putting aside their rivalry and cooperating at some point in future!
